· Cd1 In1 S2

CdInS₂ is a ternary III-VI semiconductor compound composed of cadmium, indium, and sulfur, belonging to the chalcopyrite family of materials. This compound is primarily investigated in research contexts for optoelectronic and photovoltaic applications due to its direct bandgap and tunable electronic properties that fall between its binary parent compounds. Engineers consider CdInS₂ for thin-film solar cells, photodetectors, and light-emitting devices where the layered chalcopyrite structure offers advantages in lattice matching and band gap engineering compared to simpler binary alternatives.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
